EDWARD GILLIAM, OF ALLEGHENY, PENNSYLVANIA.

lMPFlOVEMENT IN HORSE HAY-FORKS.

To all whom it may concern:

Be it known that I, EDWARD GILLIAM, of the city and county of Allegheny, and State of Pennsylvania, have invented a new and useful Improvement in Hay-Elevators; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention consists in the combination and arrangement of a pointed rod provided with a barb or prong. guides, and head-piece furnished with two slots, arranged at right angles to each other, said pointed rod thus provided and furnished being used in connection with a sliding rod and a lever, the whole being constructed, arranged, and operating in the manner hereinafter described.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

In the accompanyingdrawings,Figure lrepresent-s an isometric perspective view of m yimproved hay-elevator, showing the position of the several parts when the barb or prong is thrown outfor the purpose of taking hold in the hay. Fig. 2 represents a face view of the same, and shows the position of the several parts when the barb is thrown into its chamber and protected when entering the hay.

1n the drawings, A represents the pointed rod, which is furnished with a slot (marked 2) near its point, in which is placed the barb or prong 3, which is pivoted at a point marked 4. The upper end of the rod A is furnishedwith a head-piece, (marked B,) which is provided with two slots (marked 0 and e) and furnished with a ring, as, to which the hoisting-rope J. is attached. The rod A is also furnished with two guides, (marked 1,) which are used for the purpose of holding the sliding rod 0 in its proper position to the rod A and lever D.

The sliding rod 0 is furnished with a slot near the lower end, into which projects the point of the barb or prong 3, and is so arranged that the upward motion of sliding rod 0 will cause the barb or prong to shoot out, as shown in Fig. 1, and the downward motion of said rod will cause said barb or prong to recede within the slots in the rods 0 and A, as shown in Fig. 2.

The point of the lever D is provided with a pintle, (marked 6,) which moves in the slot marked 0 of the head-piece B. The sliding rod 0 is attached to the lever D by means of a bolt, (marked 5,) which projects through the rod 0 and lover Dinto the slot 0, in which it moves up and down in accordance with-the motion of the lever D. On the end of the bolt 5 is placed a nut to prevent the boltfrom slipping out of the slot 0.

R represents a rope or cord,which is attached to the outer end of the lever D, and is used for unshippin g said 1evers-that is to say, for bringing or throwing it from the position represented in Fig. 1 to the position represented in Fig. 2.

As the construction of my improved hayelevator and the arrangement of the several parts with relation to each other will readily be seen and understood by the skillful mechanic by reference to the accompanying drawings, I will therefore proceed to describe its operation.

When the several parts are in the position represented in Fig. 2 the rods A and O are forced down into the hay, the shoulder 8, near the point of the rod A, preventing the end ofthe rod 0 from catching in the hay by pressing on the arch of the head-piece B. I then draw up the outer end of the lever D, which will cause the pintle 6 and the inner end of bolt 5 to move in the slots 0 and 0, the pintle 6 moving in slot 0 toward rods A and O, and the bolt 5 moving upward in the slot 0. These movements will draw up the rod 0, which will cause 'the barb or prong 3 to shoot out into the hay, and when the several parts are brought into the position represented in Fig. 1, the center of the pintle 6 will be brought directly under the center of the bolt 5, which moves in the slot 0, which position of said pintle will hold the lever D in a fixed position and thereby prevent the barb or prong 3 from receding back until the elevator and its load arehoisted to the desired place. I then draw on the cord R, which will force the lever D into the position represented in Fig. 2, which movement of the lever D will cause the rod 0 to force back the barb or prong 3 into the slot2 in rod A. The elevator may then be drawn from the hay.

Having thus described the nature and conoombined, arranged, and operating substanstrnction and operation of my improvement, tially as herein described, and for the purpose what I claim as of my invention isset forth. v

The rod A, provided with the head-piece E. GILLIAM. B, furnished with slots 6 and 0, when used in Witnesses: combination with the lever D, rod 0, and JAMES J. JOHNSTON,

barb or prong 3 the whole being constructed, ALEXANDER HAYS.
